ELB Rule

Elastic Load Balancing (ELB) rules in AWS provide a way to route incoming web traffic from end-users to the back-end resources that serve the content. ELB rules define which traffic will be directed to which resources, based on criteria such as protocol, port, or domain name. The rules can be easily created and configured via AWS's Elastic Load Balancing console or API. By creating ELB rules, organizations are able to ensure that their web applications are responding quickly and reliably to user requests by routing them efficiently between back-end servers.
